Cerebral phaeohyphomycosis masquerading as a parafalcian mass: Taken together, these results demonstrate that melanin is a key cell wall polymer that could be targeted by antifungal agents.

According to microscopic examination with Lactophenol cotton blue staining for hyphae and conidia, conidiophores were brown, and ovoid conidia were located either at end or at the side of conidiophores Fig. Subsequently, using the Blast program, it was compared to oedrosoi base sequence of the reported strain in Thailand stored in GeneBanki.

Identification of sialic acids on the cell surface of hyphae and conidia of the human pathogen Fonsecaea pedrosoi. Enzyme activity was higher at acidic pHs and was strongly reduced by classical inhibitors of acid phosphatases such as sodium orthovanadate, sodium molybdate and sodium fluoride.

Accordingly, the HIV aspartyl peptidase inhibitors mentioned above also abrogated the growth of conidial forms as well as its transformation to mycelial cells Fig. Pepstatin A demonstrated a fungicidal activity against conidia in a dose-dependent fashion.
